Solomon Saddle
Solomon Saddle () is a snow saddle (elevation 1,850 m) located between the heads of Solomon Glacier and Foster Glacier, to the south of Fisher Bastion in the Royal Society Range, Victoria Land, Antarctica. The snow saddle was named by the Advisory Committee on Antarctic Names (US-ACAN) in 1994 in association with Solomon Glacier.

Solomon Glacier
Solomon Glacier () is a glacier on the south side of Fisher Bastion which flows west from Solomon Saddle to enter Potter Glacier in the Royal Society Range, Victoria Land. Named by Advisory Committee on Antarctic Names (US-ACAN) in 1994 after Susan Solomon, NOAA, atmospheric chemist who has been a leader in the study of upper atmospheric physics in Antarctica. At the time of naming, Chairman of the Office of Polar Programs Advisory Committee, National Science Foundation (NSF).

Foster Glacier
Koettlitz Glacier is a large Antarctic glacier lying west of Mount Morning and Mount Discovery in the Royal Society Range, flowing from the vicinity of Mount Cocks northeastward between Brown Peninsula and the mainland into the ice shelf of McMurdo Sound. It was discovered by the British National Antarctic Expedition (1901–04) which named it for Dr. Reginald Koettlitz, physician and botanist of the expedition. See also * Bulwark Stream * List of glaciers in the Antarctic There are many glaciers in the Antarctic. This set of lists does not include ice sheets, ice caps or ice fields, such as the Antarctic ice sheet, but includes glacial features that are defined by their flow, rather than general bodies of ice. ...

Fisher Bastion
Fisher Bastion () is a high rectangular massif, high, between the upper reaches of Potter Glacier and Foster Glacier, southeast of Mount Huggins in the Royal Society Range of Victoria Land, Antarctica. It was named by the Advisory Committee on Antarctic Names in 1994 after Commander Dwight David Fisher, U.S. Navy, Commanding Officer of the Naval Support Force, Antarctica, 1987–89; Fisher Peak in Palmer Land Palmer Land () is the portion of the Antarctic Peninsula, Antarctica that lies south of a line joining Cape Jeremy and Cape Agassiz. This application of Palmer Land is consistent with the 1964 agreement between the Advisory Committee on Antarctic N ... was also named after him.

Royal Society Range
The Royal Society Range () is a mountain range in Victoria Land, Antarctica. With its summit at , the massive Mount Lister forms the highest point in this range. Mount Lister is located along the western shore of McMurdo Sound between the Koettlitz, Skelton and Ferrar glaciers. Other notable local terrain features include Allison Glacier, which descends from the west slopes of the Royal Society Range into Skelton Glacier. Discovery and naming The range was probably first seen by Captain James Clark Ross in 1841. The range was explored by the British National Antarctic Expedition (BrNAE) under Robert Falcon Scott, who named the range after the Royal Society and applied names of its members to many of its peaks. For example, Mount Lister was named for Lord Joseph Lister, President of the Royal Society, 1895–1900. The Royal Society provided financial support to the expedition and its members had assisted on the committee which organized the expedition. Geology The Royal ...

Victoria Land
Victoria Land is a region in eastern Antarctica which fronts the western side of the Ross Sea and the Ross Ice Shelf, extending southward from about 70°30'S to 78°00'S, and westward from the Ross Sea to the edge of the Antarctic Plateau. It was discovered by Captain James Clark Ross in January 1841 and named after Queen Victoria. The rocky promontory of Minna Bluff is often regarded as the southernmost point of Victoria Land, and separates the Scott Coast to the north from the Hillary Coast of the Ross Dependency to the south. The region includes ranges of the Transantarctic Mountains and the McMurdo Dry Valleys (the highest point being Mount Abbott in the Northern Foothills), and the flatlands known as the Labyrinth. The Mount Melbourne is an active volcano in Victoria Land. Early explorers of Victoria Land include James Clark Ross and Douglas Mawson.

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Susan Solomon
Susan Solomon (born January 19, 1956 in Chicago) is an American atmospheric chemist, working for most of her career at the National Oceanic and Atmospheric Administration. In 2011, Solomon joined the faculty at the Massachusetts Institute of Technology, where she serves as the Ellen Swallow Richards Professor of Atmospheric Chemistry & Climate Science. Solomon, with her colleagues, was the first to propose the chlorofluorocarbon free radical reaction mechanism that is the cause of the Antarctic ozone hole. Solomon is a member of the U.S. National Academy of Sciences, the European Academy of Sciences, and the French Academy of Sciences. In 2002, ''Discover'' magazine recognized her as one of the 50 most important women in science. In 2008, Solomon was selected by ''Time'' magazine as one of the 100 most influential people in the world. She also serves on the Science and Security Board for the Bulletin of the Atomic Scientists.

Ozone Hole
Ozone depletion consists of two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere, and a much larger springtime decrease in stratospheric ozone (the ozone layer) around Earth's polar regions. The latter phenomenon is referred to as the ozone hole. There are also springtime polar tropospheric ozone depletion events in addition to these stratospheric events. The main causes of ozone depletion and the ozone hole are manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam- blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as ozone-depleting substances (ODS). These compounds are transported into the stratosphere by turbulent mixing after being emitted from the surface, mixing much faster than the molecules can settle. Once in the stratosphere, they release atoms from the halogen group through photodissociation, which catalyz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Passes Of Victoria Land
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable ...
